SPECIFICATION forming part of Letters Patent 191' 0,368,986, datedAugust 30, 1887. v Application filed February 28,1887. Serial No.229,151. (No model.)

To all whom it may concern:

Be it known that I, STEBBINS S. WEBBER,

a citizen of the United Statesyresiding inLa Porte, in thecountyof-La'Porte and State of Indiana, have invented a new and usefulImprovement in Grates for Stoves, of which'the following is aspecification.

, I This invention relates to an improved construction of grates forwood and soft-coal stoves.

The object of the invention is to provide for a central draft and for anoutside or surrounding draft, either one of which may be alternatelyused, the grate being so contrived that the closing of the outsidesurrounding or circumferential draft, will open the central draft, andvice versa; and it consists, further, in furnishing the grate above thecentral draft with a deflecting-plate for turning the currents from thecentral draft outward to cause the heated gases and flame to impingeagainst the sides of the stove in their passage to the chimney-flue,thus producing a gain in the heating effect of the stove.

I strictly necessary to embody the general fea-.

In the accompanying drawings, which form a part of this specificationandin which similar letters of reference indicate like parts, Figure 1 is aperspective view of a stove of the kind in which my grate is employed.Fig. '2 is a plan view of the grate when made in circular form, showingthe same in position to cause the central draft. Fig. 3 is a section ofFig. 2 on the line 3 3. Fig. 4 is a plan view of the same grate in theposition in which the central draft is closed and the outside draftopen, and Fig. 5 is a section on the line 5 5 of Fig. 4. 1

' In the said drawings, A represents the stationary part of the grate,which is suitably secured to the stove.

B is the movable part of the grate,pivoted t0 the stationary part so asto oscillate thereon. I prefer toraise the central portion of the twoparts A and B into a dome form, as indicated in Figs'. 3 and 5; but thisis not tures of my invention. Both plates A and B are perforated with aseries of openings, 0 D, so placed relatively to each other upon theplates that when the openings C, constituting the outer series,coincidewith each other, as at Fig. 4, the inner series, D, do notcoincide with each other, and when the inner series, D, coincide orregister with each other the outer series do not. In short, when theouter part of the grate is open for the draft, the innerpart is closed,and vice versa.

A handle, E, projecting from the movable part of the grate, serves tooperate the same from the outside of the stove either to change thecharacter of the draft or to shake the grate, as required.

Above the center of the grate I place, in order to obtain the bestresults, a deflector, F, which, when the central draft is open, as atFigs. 2 and 3, causes the currents of air to be deflected, as indicatedby the arrows in gular inform, in which case the inner and outer seriesof perforations may be opened and closed by means of a rectilinearmotion, in which case the moving plate would need to be slotted in orderto pass the support of the central deflecting-plate, if the latter isemployed.

There may be any number of draft-openings required in the grate; butIprefer to have more than one in each series.

I claim- 1. The two part grate, one part movable upon the other, eachprovided with two series of draft-openings, so placed relatively to eachother that the opening of the outside series closes the inside seriesand the opening of the inside series closes the outside series, substan-STEBBINS S. WEBBER.
